Application filed July 28, 1920. Serial No. 399,584.

To all whom it may concern:

Be it known that I, FILMORE M. PRICE, a citizen of the United States, residing at Floydada, in the county of Floyd and State of Texas, have invented new and useful Improvements in Attachments for Broadcast Headers, of which the following is a specification.

This invention relates to harvesting machines, particularly to headers, and has for its object the provision of an attachment whereby a broad cast header may be adapted for use in heading maize or other similar grain growing in rows.

An important object is the prov1s1on of an attachment of this character which is adj ustable for different distances between succes-V sive rows, and which is so constructed that a plurality of rows may be headed simultaneously.

Another object is the provision of a device of this character which is provided with a guide located at a comparatively high elevation and which is adapted to engage and force down excessively high heads, so that they will be properly cut with the normal heads, this guide being adjustable;

Another object is the provision of a device of this character including means whereby the elevators'and their associated parts may be swung upwardly or downwardly as desired, whereby to secure the pro-per adj ustment.

An additional object is the provision of'a device of this character which will be comparatively simple and inexpensive in manufacture, highly efficient in use, durable in service, and a general improvement 111 the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter" more fully described and claimed" and illustrated in the accompanying drawings in which- Figure 1 is a plan view of a header showing my device applied thereto.

Fig. 2 is a side elevation with parts broken away and in section,

Fig 3 is a cross'sectional view on the line 38 of Fig. 2,

Fig. 4 is a cross sectional view on the line 44 of Fig. 1,

Fig. 5 is a fragmentary detail elevation showing the adjustable mounting of the elevator drive,

Fig. 6 is a detail sectional view showing the adjustment of the hangers for the upper ends of the elevators,

Fig. 7 is a detail sectional view of an adjustable bearing for the shaft driving the elevators, and

Fig. 8 is a detail sectional view of the hinge mounting for the elevators.

Referring more particularly to the drawings, the letter A designates the platform of a broad cast header and B designates the sickle. Other parts of a well known broad cast header are also shown but it is believed that a detailed description thereof is unnecessary.

In carrying out my invention I provide a shaft 10, square in cross section, suitably mounted above the platform A and this shaft is provided at one end with a sprocket 11 overwhich is trained a chain 12 driven from the bull wheel of the header. Disposed upon the shaft 10 at spaced intervals and slidably adjustable thereon, are bevel pinions 13 which mesh with bevel gears 14: secured upon short shafts 15 journaled through L- shaped brackets 16 slidable upon the shaft 10. The upper ends of the shafts 15 are mounted upon a transverse rod 16 and held in adjusted positions thereon by set-screws 16 The rod 16 is supported in bearings 16 which are mounted on bars 28 secured above the platform. Slots 28 are formed in the bars 28' and through these slots pass the bolts 16 which hold the bearings 16 This arrangement permits adjustment of the bean ings 16 and shaft 16*. Secured upon the shafts 15 are sprockets 17.

The numeral 18 designates elevators arranged at intervals and each comprising a pair of boards 19 having their confronting edges curved, as shown at 20, to define flaring. entrance opening between them and a relatively narrow out-let opening. Secured at the curved edgesQO are guide bars or strips 20. Journaled at the free end of each elevator is a sprocket 21 about which is. trained a chain 22 which is also trained about the associated sprocket 17 and which carries fingers 22 Journaled through each elevator is a shaft 24 upon which is mounted a sprocket-23 engaged by the chain 22, Se-

cured upon the upper end of the shafts 24 are beater members 25 of ordinary con-struction.

Secured upon the platform A is a plurality of inverted U-shaped bars 26 which are adjustably connected with the platform by means of bolts 27 which pass through selected holes 29 in the depending arms of the bars 26. Secured upon the bars 26 are up standing brackets 30 provided. with holes 31 through selected ones of which are passed bolts 32 which pass through the arms 33 depending from the bars 28. By this con struction it will be seen that the bars 28 may be raised and lowered.

Disposed below the platform is an elongated loop-like guide .34 at each end portion of the platform. Any desired number of similar guides may be interposed between these endmost guides. Extending fromthe guides 34 are upwardly and rearwardly extending arms 35 which'are slotted, as shown at 36, for the passage of securing bolts 37, whereby the connection is adjustable. Extending from each guide 34 is a. much longer bar or strip 38 which has its rear end slotted, as shown at 39, for passage of a bolt 40 which secures the bar 38 to the rear portion of the platform. Extending forwardly from the guides 34 are-downwardly inclined bars 41 which are slotted at their forward ends, as shown at 42, for the passage of bolts 43 which extend through members 44 secured upon the lower sides of the elevators.

The elevators are mounted for vertical swinging movement and this mounting comprises a hinge-leaf 45 for each elevator board slidably mounted upon the forward edge of the platform A and held in position by a bolt 46 passing through a lateral slot 47 in the leaf and into the forward edge of the platform. Hinged upon the upper edge of each leaf 45 is a leaf '48 disposed against the underside of each elevator board and provided with slots 49 through which pass bolts 50 whereby able.

Disposed within the guides 34 are slidable blocks 51 which carry a rod or shaft 52. Threaded through the lower ends of the guides are upwardly extending screws 53 which engage the blocks 51 whereby sition of the rod 52 may be varied at will.

Secured to the forward end portion of the bars 28 are bars 54 which are formed at their forward ends withfl'guide loops 55 from which extend downwardly inclined bars 56 secured to the depending forward ends of the bars 26. 'Extending upwardly from the bars 56 are rods 57 which have their ends the connection is adjustthreaded passing through the bars 54 and provided with clamping nuts 58. This particular construction is necessary 4 to permit adjustment, depending upon the height at which the bars 28 are disposed. Disposed the po-.

through the guide loops 55 is a rod or shaft 59 into which extend screws 60 slidable within slots 61 in the loops. The purpose of the rod 59 is to press down excessively high heads of grain.

It will be observed that the brackets 30 are adjustable longitudinally of the bars 26 by means of bolts 62 which pass through the foot portions of the brackets and through holes 63 in the bars 26.

it should also be stated that the shaft 10 may be shifted forwardly or rearwardly with respect to the platform A by virtue of the fact that it is journaled within bearings 64 carrying bolts 65 passing through slots 66 in the bars 26.

The operation of the device is as follows:

When it is desired to convert the ordinary broad cast header into a header for maize or other grain growing in rows, it is necessary to apply the pairs of elevators l8 and to adjust these pairs so that the successive pairs will be in position to straddle successive rows \of grain. This adjustment is easily accomplished byyirtue of the fact that the leaves 45 which carry the elevators are slidable along the forward edge of the header platform and that the brackets or hangers 16 which are secured to the upper ends of the elevators are slidable alon the shaft or rod 16". It will be observed that as these hangers are moved'thedrive pinions 13 for the elevators will slide along thevshaft l0. vVith the parts constructed and arranged as shown and described, when the header is drawn along a field with the elevators in straddling relation to 'thc rows,'the grain will pass between the boards thereof and will be carried'by the fingers to the sickle B in the ordinary manner. As the shaft 10 is rotated by. the bull wheel it will be seen that by virtue of the pinions 13 and 14 and sprockets 17 the sprocket chains 22 will move simultaneously toward the platform at the inner edges of the elevator boards.

As the sprockets 23 are engaged by the inner runs of the chains 22 the heaters 25 will be moved toward each other so as to pull the cut heads onto the platform A. The disposition of the heads after reaching the platform, forms no part of the present invention and description of any auxiliary or additional structure is therefore omitted.

WVhen-ever it is desired to Swing the elevators upwardly, it is necessary to loosen the bolts holding the various bearings andbrace bars so that the elevators may be swung 7 upon thepivots at the top of the leaves 45.

When this is done it is-of course necessary that the bearings 16 be adjusted rearwardly along the bars 28, that the bars 28 be lowered along the brackets 30 and that the bearings 64 be shifted. All these adjustments may be easily made to allow for any variations desired.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claii'ns.
